Revisions to the Unregulated Contaminant Monitoring Regulation (UCMR 3) for Public Water Systems (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Revisions to the Unregulated Contaminant Monitoring Regulation (UCMR 3) for Public Water Systems (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The 1996 amendments to the Safe Drinking Water Act (SDWA) require that the United States Environmental Protection Agency (EPA or the agency) establish criteria for a program to monitor unregulated contaminants and publish a list of up to 30 contaminants to be monitored every five years. This final rule meets the SDWA requirement by publishing the third Unregulated Contaminant Monitoring Regulation (i.e., UCMR 3), listing the unregulated contaminants to be monitored and addressing the requirements for such monitoring. This final rule describes analytical methods to monitor for 28 chemical contaminants and describes the monitoring for two viruses. UCMR 3 provides EPA and other interested parties with scientifically valid data on the occurrence of these contaminants in drinking water, permitting the assessment of the number of people potentially being exposed and the levels of that exposure. These data are one of the primary sources of occurrence and exposure information the agency uses to develop regulatory decisions for these contaminants. In addition, as part of an Expedited Methods Update, this rule finalizes amendatory language for a drinking water inorganic analysis table ("Inorganic chemical sampling and analytical requirements") in the Code of Federal Regulations (CFR). This minor editorial correction to the table does not affect the UCMR program.
